Dynamics of soil water content in the rhizosphere
Andrea Carminati,Ahmad B. Moradi,Doris Vetterlein,Peter Vontobel,Eberhard Lehmann,Ulrich Weller,Hans-Jörg Vogel,Sascha E. Oswald +7 more
TL;DR: In this article, the authors used neutron radiography to image water content distributions in soil samples planted with lupins during drying and subsequent rewetting, and derived the distinct, hysteretic and time-dependent water retention curve of the rhizosphere.
Journal ArticleDOI
In situ diagnostic of two-phase flow phenomena in polymer electrolyte fuel cells by neutron imaging: Part A. Experimental, data treatment, and quantification
Denis Kramer,Jianbo Zhang,Ryoichi Shimoi,Eberhard Lehmann,Alexander Wokaun,Kazuhiko Shinohara,Günther G. Scherer +6 more
TL;DR: In this article, a unique experimental approach for the investigation of two-phase flow phenomena in technical PEFC has been realized, and algorithms for an enhanced quantitative evaluation of the obtained images are presented and successful application to the data demonstrated.
Journal ArticleDOI
The ICON beamline – A facility for cold neutron imaging at SINQ
Anders Kaestner,Stefan Hartmann,G. Kühne,G. Frei,Christian Grünzweig,L. Josic,Florian Schmid,Eberhard Lehmann +7 more
TL;DR: The beamline for Imaging with COld Neutrons (ICON) at Swiss spallation neutron source (SINQ) at Paul Scherrer Institut has a flexible design to meet the requests from a wide user community.
Journal ArticleDOI
Neutron Phase Imaging and Tomography
TL;DR: A setup consisting of three gratings yields quantitative two- and three-dimensional images depicting the quantum-mechanical phase shifts of neutron de Broglie wave packets induced by the influence of macroscopic objects, dramatically reducing the required measurement time for computed phase tomography.
Journal ArticleDOI
In situ observation of the water distribution across a PEFC using high resolution neutron radiography
Pierre Boillat,Denis Kramer,Bernhard C. Seyfang,G. Frei,Eberhard Lehmann,Guenther G. Scherer,Alexander Wokaun,Y. Ichikawa,Yutaka Tasaki,Kazuhiko Shinohara +9 more
TL;DR: In this paper, the water distribution across the membrane electrolyte assembly (MEA) of a working polymer electrolyte fuel cell (PEFC) was observed in situ using neutron radiography.
